摘　　要：简要介绍了中国ＣＪＢ、美国ＬＲＦＤ、日本ＡＩＪ和欧洲ＥＣ４规范中有关方钢管混凝土基本构件的设计方法，并将以上方法的计算结果和收集到的大量试验结果进行了分析对比，其中包括１５８个轴压、１５个纯弯及１４７个压弯构件，结果表明各设计规范均能较好地估算构件的承载力，但ＬＲＦＤ、ＡＩＪ和ＥＣ４的计算结果整体上偏于安全，ＧＪＢ的计算结果则和试验结果较为一致，能较好反映构件的实际承载力。Briefs the design methods for concrete filled square steel tubular members in different codes including LRFD(American), AIJ(Japan), EC4(Europe), GJB(China) compares the calculation results with there obtained through a lot of tests including tests conducted with 158 axial loaded members,15 bending members and 147 compression-bending members, and concludes from analytical results that all the design codes can he used to reasonably evaluate the bearing capacity, but LRFD, AIJ, EC4 are somehow a bit conservative, and GJB' results are in good agreement with tests results.
